Patent EP-0398180-A2 (EP)
Inventor: MUMOLO ENZO
IPC: G10L25/93
Filed: 1990-05-11
Abstract: The spectra of voiced sounds lie predominantly at or below about 1 kHz. The spectra of unvoiced sounds lie predominantly at or above about 2 kHz. It is known to determine the lower- and higher-frequency energy components contained in a sound or sound element, to compare these energy components, and to use the result of the comparison to make a voiced-unvoiced decision. Since the distributions relative to voiced and unvoiced segments are overlapped, false decisions are liable to occur. The invention is predicated on the fact that a change from a voiced sound to an unvoiced sound or vice versa always produces a clear shift of the spectrum, and that without such a change, there is no such clear shift. From the lower-­and higher-frequency energy components, a measure of the location of the spectral centroid is derived which is used for a first decision. Based on the difference between two successive measures, a second decision is made by which the first can be corrected.

Abstract: There is provided a one-dimensional MIM array hav­ing MIM structures (15) arranged on an insulative sub­strate (11) in a lateral direction and each used as a unit for storing a signal charge, for sequentially stor­ing and transferring the signal charges between the adjacent MIM structures (15). With the above element structure, the signal charge is transferred in each of the MIM structures (15) in a thickness direction (depth direction) thereof and stored in a capacitor (16). The signal charge stored in the capacitor (16) is sequ­entially transferred in a lateral direction or to the next MIM structure (15). In order to drive the above charge transfer device, transfer pulses applied to a plurality of MIM structures (15) constituting a one-­dimensional MIM array are controlled to sequentially transfer and store the signal charges into the MIM structures starting from the MIM structure which is pro­vided on the output terminal side of the one-dimensional MIM array. At the time of reading out the signal charge, signal charges are sequentially read out and transferred from the MIM structures starting from the MIM structure which is provided on the output terminal side.

Abstract: An opaque, abrasive removable fragrance releasing composition, coating and article are provided. A method of releasing a fragrance while revealing a message is also provided. The composition can be a dispersion containing opaque particulate material, rupturable microcapsules containing a fragrant material, a binder for adhering the opaque particulate material and the microcapsules when the composition is applied to and dried on the substrate, and a solvent compatible with these materials.

IPC: C23C16/44

Abstract: The disclosure relates to an epitaxial reactor system (100) and features several improvements providing for enhanced gas flow control and, thus, deposition uniformity. Gross reactant gas flow is set by a main flow controller (342), which delivers unequal amounts to a reaction chamber via two nozzle assemblies (310,320). A supplemental flow (344) controlled by an auxiliary flow controller (346) is used to balance the flow rates through the nozzle assemblies so as to reduce spiralling of the gas flow within the chamber. Vertical ridges (350), on a shroud (120) within the reaction chamber help guide incoming gases vertically, further minimizing spiralling. The direction of gas flow from each nozzle assembly is controlled by two actuators, one (610) controlling orientation along a coarse diagonal to obtain an overall vertical uniformity of deposition; the other (614) actuator controls orientation along a fine diagonal to balance inter- and intra-wafer deposition uniformity. This arrangement optimizes the convenience in attaining vertical uniformity. Within each nozzel assembly, (724,726) a nozzle (508) includes an apertured ball (508) which pivots between two Teflon rings (724,726) which are urged against the ball by a lock nut (728). The compression and frictional forces are adjusted so that a nozzle orientation can be maintained while allowing orientation to be changed by applying force through the actuators. This avoids having to disassemble components to reorient the nozzles.

Abstract: In a method and apparatus for rendering a trimmed NURBS surface representing a mapping from U and V parametric coordinates to X, Y and Z geometric coordinates and having a trimming region bound by a trim polyline, the UV parametric surface is divided into contiguous U and V intervals intersecting to form UV rectangles, the trim polyline intersecting a subset of the UV rectangles to divide each of the UV rectangles of the subset into at least one polygon lying within the region and at least one polygon lying outside the trimming region. For each UV rectangle intersected by the trim polyline, the vertices of each polygon within the trimming region formed by the intersection of the trim polyline and the UV rectangle is determined, and vertex data for the vertices so determined is provided to a concave polygon processor 104 to render the polygon. For each V interval intersected by the trim polyline, polyline data stored in a global memory 102 is read by the graphics processor, and the polyline defined by the read data clipped to form a V-clipped polyline defined by V-clipped data which is stored in local memory associated with the processor. The graphics processor then processes the V interval using the V-clipped polyline data stored in local memory.
